I wrote earlier about the heart strings pins....but wanted to add another comment....
After they are dried you can still add "wads" of cut up strings of a certain color....such as, one friend really likes red, so I cut some strands of red threads and kind of laid them across the heart...and another friend loves light blues so I took DMC embrodiery floss and gave them a dab of glue and draped and wrapped them around the heart.
Glad you all like this idea it is fun to play with our treads...other than wearing them. lol
